Can any plumbers please help me? What is this component (see pic) on the vent pipe of my vented hot water system? It is a very simple system, just an immersion with hot water cylinder on the ground floor and cold tank in the loft. This piece is just before the hot water pipe (from the top of the cylinder) goes back into the top of the cold water tank.
I’m not 100% sure what it is (shut off valve or some sort of pressure valve) and why it is there. The diagrams I can find online don’t include this bit.
Thanks !
